CUSHION.

Application led March 17, 1921.

To all whom z't may concern: p

Beit known that I,- JULIAN S. Famos, a citizen of the United States of America, residin at the city of St. Louis, State of Missouri, -lnited States of America, have-invented a certain new and useful Cushion, of which the following is such a full, clear, and exacty description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention, which is particularly adapted as an automobile cushion,` consists of an ably elongated in form and providing a dash air-tight cover enclosing suitable springs and provided with an air vent consisting of one or more passages permanently open during the operation of the device so as to provide a dash pot or dampeningeffect,auxiliary to the spring effect, together with means for varying the effective area of such vent so as to adapt the cushion for use by persons of different weights. l

In the accompanying drawings whichillustraite one form of cushion made in accordance with my invention, Figure 1 is a vertical cross section, Figure 2 1s a bottom plan View, and Figure 3 an enlarged section taken on the line 3 3 of Figure 2.

The base of my cushion comprises a frame work 5, preferably 'having cross pieces 6, and a bottom board 7 which may be formed of card board or other suitable thin ,material Resting upon the base are anumber of springs each consisting of two parts 8 and 9 secured together by strips 10 of steel o'r other suitable material'. ASurrounding the springs is the cover consisting of an outer part 11 preferably of leather, an inner part 12 of canvas or sheeting and an intermediate layer of cotton wadding 13, the several parts forming an air-ti ht covering. Formed in the bottom board is an opening 14 preferpot or dampening effect auxiliary to the action of the springs. Below the opening 14 is a sheet of metal 15 preferably setinto the cross pieces 6 and provided with an opening 16 corresponding in size and `.shape t0 Specification of .Letters Patent. I

- will be supplemented by t e dash pot or dampening effect of the air as it passes in and out of the vent 14 and the effective area of this opening can readily be varied to adapt this effect to the weight to which the cushion is to bear.

yI am aware that it has been heretofore proposed to provide a spring cushion with la valved opening, the valve being adapted to close under abnormal shocks, and do not desire to claim such as my invention as it is essential to the proper operation of my device that the air vent be permanently open lduring the operation of the device and that said vent be capable of adjustment to vary its effect.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a device ofthe class described, the combination with a base,-of springs carried by said base, an air tight cover for said springs, a bottom board carried by said base and provided with an air vent, and adjustable means for varying the effective area of said vent.

2. In a device of the class described, the'| combination With a base, of springs carried by said base, an air-tight cover for said springs, a bottom board carried by said base `and provided with an air vent, a plate car-
